What are the notifications available in android?

 A notification is a message that we can display to the user outside of our application's normal UI.

We have different types of Notifications

Toast Notification − It will show a pop-up message on the surface of the window

Status Bar Notification − It will show notifications on the status bar

Dialogue Notification − It is an activity related notification

LockScreen Notifications 


In Android version 8.0 (Oreo) and above to create notifications we need to create Notification Channel.
